| 摘要 |
The invention concerns a washing and extracting head for an apparatus or automaton designed to wash microplates and a corresponding apparatus. Said washing and extracting head is mobile above the microplate(s) in treating position and comprises a alignment of dispensing needles or tubes and an alignment of suction needles or tubes associated in pairs, the number of the two types of needle pairs being equal to the number of wells per column or per row and the spacing between two adjacent pairs being equal to the spacing between two adjacent wells of the same column or row. The invention is characterised in that the suction needles (5), and the parts of the consecutive suction and/or recovery circuit (5'), have a passage cross sectional diameter not less than the largest transverse dimension of the sample supports (3) present in the wells (2') and said head (1) comprises or co-operates with at least means retaining the microplate (2) to be washed or preventing it from being lifted, at least during the suction extraction phase. |
